ABSTRACT
OBJECTIVE: To evaluate the prevalence of and the associated factors for metabolic syndrome (MS) among Latin American HIV-infected patients receiving antiretroviral therapy (ART) using baseline data from the RAPID II study. METHODS: A longitudinal study to evaluate the metabolic profile, cardiovascular disease (CVD) risk and associated treatment practices to reduce this risk has been conducted in seven Latin American countries (the RAPID II study). Adult HIV patients with at least six months of RT were enrolled. MS was defined following ATP-III criteria. Demographic and anthropometric data, serum biochemical and clinical parameters were compared in patients with and without MS using bivariate and multivariate analysis. RESULTS: A total of 4,010 patients were enrolled, 2,963 (74 percent) were males. Mean age (SD) was 41.9 (10.0) years. The prevalence of MS was 20.2 percent. Females had higher prevalence of MS than males (22.7 percent vs. 19.4 percent, p = 0.02). MS was driven by high triglycerides, low HDL-cholesterol and high blood pressure (HBP). Patients with MS had higher 10year CVD risk: 22.2 percent vs. 7.4 percent, p < 0.001. Age (OR: 1.05 per year), female gender (OR: 1.29), family history of CVD (OR: 1.28), CD4 cell count (OR: 1.09 per 100 cell increase), and protease inhibitor based-ART (OR: 1.33) correlated with MS in the multivariate analysis. CONCLUSIONS: Prevalence of MS in this setting was similar to that reported from developed countries. MS was driven by high triglycerides, low-HDL and HBP, and it was associated with higher risk of CVD. Traditional risk factors, female gender, immune reconstitution, and protease inhibitor based-ART correlated with MS.
